AFNI Message Board

Hello AFNI gurus,
A minor question and observation. Why did the default EPI masking in afni_proc.py change from applying 3dAutomask with dilation of 1 voxel to using no dilation? I noticed this while comparing coverage maps from two different datasets, one processed with a more recent version of AFNI in which the dilation is not applied, and just want to be consistent (easy enough to rerun 3dAutomask). Just curious, what is the justification for this change? Also, wanted to point out that the afni_proc help doc (https://afni.nimh.nih.gov/pub/dist/doc/program_help/afni_proc.py.html) still says that a dilation of 1 voxel is applied by default.
